Correct Option: B. The discovery of a snake in the roof causes panic among the students. Detailed Explanation: In Chapter 5 of "The Lekki Headmaster," the discovery of a snake in the roof is a pivotal moment that significantly heightens the tension in the story. This event is crucial for several reasons:

1. Immediate Reaction: The presence of a snake creates an immediate sense of fear and panic among the students. Snakes are often associated with danger and unpredictability, which can lead to heightened emotions and chaos in a school environment. This reaction is realistic and relatable, as many people have a natural fear of snakes.
2. Impact on School Environment: The discovery disrupts the normal flow of school activities. Students are likely to be distracted, anxious, and unable to focus on their lessons. This disruption can lead to a breakdown in order, which is critical in a school setting where discipline and focus are essential for learning.
3. Character Development: This event also serves as a catalyst for character development. It allows us to see how different characters react to fear and crisis. For instance, some students may show bravery, while others may panic, revealing their personalities and relationships with one another. The headmaster's response to the situation can also showcase his leadership qualities and how he handles emergencies.
4. Foreshadowing: The snake can symbolize underlying issues within the school or community, such as hidden dangers or problems that need to be addressed. This foreshadowing can create suspense and anticipation for future events in the story.

Why Other Options Are Weaker:

• A. A major storm disrupts school activities: While a storm can create tension, it is a more common and less personal threat compared to the discovery of a snake. A storm may cause logistical issues, but it does not evoke the same level of immediate fear and panic among the students as a snake would.
• C. The headmaster announces a surprise inspection: This event could create tension, but it is more about academic pressure than a physical threat. The fear of being unprepared for an inspection is less visceral than the fear of encountering a snake, which can lead to a more intense emotional response.
• D. A new teacher arrives and changes the class schedule: While this can cause some disruption, it is generally a manageable situation. The arrival of a new teacher may create curiosity or excitement rather than the intense fear and panic that a snake would invoke.

Summary of Key Points:

• The discovery of a snake in the roof creates immediate panic among students, heightening tension in the story.
• This event disrupts normal school activities and showcases character reactions to fear.
• It serves as a symbol for deeper issues within the school environment.
• Other options, while potentially disruptive, do not evoke the same level of emotional response as the snake incident.

This analysis helps to understand the significance of the snake discovery in Chapter 5 and its impact on the narrative of "The Lekki Headmaster."
